The Makita 18V LXT Lithium-Ion Cordless Heated Jacket features three heat settings (high, medium, and low) for precise heating control with five core heat zones on the left chest, right chest, back, and both pockets for optimum heat distribution. On the low setting, the jacket has a run-time of up 35 hours with an 18V LXT 6.0Ah battery (battery sold separately). For increased durability, the jacket's polyester shell adds greater wind and water resistance while the stretchy side panels help to increase mobility. The jacket's fleece interior adds an extra layer of warmth and comfort.
